Topic: GE GSH25JFTACC defrost problem (Read 1774 times)

The original complaint was not cooling. This is a sxs with the board on the back. the evaporator was full of frost. I put a jumper between line and defrost on the blue connecter at the bottom of the board. Heater comes on. I defrost it and install a new board. One week later I get the call again and sure enough its not defrosting.I do it all again and install another board. Two months later I get the call again. Sure enough same problem so I go through the procedure a third time. That was two weeks ago and so far no call. The boards don't have any burned spots or overheated components. Is there another part I should also be changing?

I second the evap thermistor. If you check the resistance, it should be obvious. It will get moisture inside and a lower resistance. Since the thermistor is designed to reduce resistance as the temperature increases, the computer reads the low resistance as a higher temperature and won't energize the heater.
